hunting. Socialists were also elected to local office and received the nation's highest vote count per capita for the party's candidate, Eugene V. Debs in 1916. The Jim Crow Law in Oklahoma was struck down by the United States Supreme Court, but a special session was called by the Democratic governor and focused on voting laws that limited black voter participation. The Ku Klux Klan and the civil rights struggles of the World War I era came to Oklahoma in the 1920s, leading to the Tulsa race massacre, lynchings and other violence. Following the practical destruction of the Socialist party in the aftermath of the Green Corn Rebellion, state politics became a two-party system that continued to exclude black voters. New Deal coalition At the U.S. Presidential level, Oklahoma's electoral college vote was a reliable part of Franklin D. Roosevelt's "New Deal" coalition (which began in the U.S. election of 1932). Oklahoma did support President Eisenhower in 1952 and 1956, but then returned to supporting the Democrats in 1964 (Oklahoma split its electoral college vote Nixon–Byrd 7–1, due to a maverick elector, commonly referred to as a faithless elector, in 1960). During this same period, Oklahoma's Governors, legislature, and delegation to Congress continued to be dominated by the Democratic Party. However, there was political infighting over deficit spending in the late 1930s, leading to a successful bipartisan push for a 1941 constitutional amendment requiring legislators to pass a balanced budget. Leon C. Phillips, who opposed New Deal programs, rose to prominence, first as Speaker of the Oklahoma House of Representatives and later as governor. Southern strategy During the presidential campaign in 1968, Oklahoma was targeted by the Republican Party to be included in what was called the Southern Strategy. Beginning with the second Presidential campaign of Richard Nixon (who appealed to Oklahoma voters on the issue of law and order), Oklahoma gradually changed in its voting pattern in national elections to become an increasingly reliable Republican state for presidential tickets. President George W. Bush carried Oklahoma twice (by a wide margin), in 2000 and 2004, for example. Starting with the 2004 election results, every county in Oklahoma has gone to the Republican candidate. In 2008, Oklahoma was the only state in which every county was carried by John McCain. Gradually, the success of the Republican Party began to translate into Congressional, legislative, and other local political races. 21st century By
